Auto merge of #85352 - Xanewok:update-rls, r=Xanewok

Update RLS

Contains rust-lang/rls#1736. With #82208 merged, this should now close #85225. Tested locally with `./x.py test src/tools/rls` and seems to be working as expected.

I noticed the rustfmt merge didn't trigger toolstate upgrade (because we pruned most but not all of the related machinery?), so I'd rather get this rubber-stamped by someone more knowledgeable with infra/the merged changes in case I missed something and need to include something else here to unbreak the RLS toolstate.
